WALL-BUILDING APPARATUS.

Application filed November 24, 1926. Serial No. 150,615.

My invention relates to means for mold ing or forming hollow walls or the like, employing concrete or other plastic materials; and the same has for its object more particularly to provide a simple, reliable and ellicient apparatus for that purpose which may be readily removed after the wall molding or it'orming operation.

Further, said invention has for its object to provide apparatus of the character specified in which a core is employed to form an intermediate air space in the wall portion or' the like being constructed, and in which said core may be readily actuated to permit of the removal of the same from position without damaging or injuring the newly molded construction.

Further, said invention has for its object to provide apparatus of the character specified in which the air space forming member thereof consists of a core havingwalls movable towards and away from each other, and in which the actuating means therefor is disposed between said walls to ermit of the application of the actuating f drces thereto at points located within the confines of said walls and arranged symmetrically relative thereto.

Further, said invention has for its object to ",nrovide apparatus of the character specilied in which the member or core serving to form an air space in the wall portion to be constructed is collapsible to permit of the ready removal thereof when the wall portion is completed, and in which the actuating means for said core serves to brace the same in the operative or molding position thereof.

Further, said invention has for its object to provide apparatus of the character specified in which an auxiliary core is associated with the cores of wall molding orforming machines or the like to form a continuous air space in the wall portion being constructed, and in which said auxiliary core is collapsible to permit of the ready removal thereof from position.

Further, said invention has for its object '0 provide apparatus of the character speciiicd in which the walls of thecollapsible core are maintained against movement towards each other at the outer ends thereof by the wall forming or molding machines or clements associated therewitlfi.

Other objects will in part be obvious and in part be pointed out hereinafter;

To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

Referring to the drawings, I have illustrated, as one example, my invention in connection with molding or wall building ma chines of the type shown, described and claimed in the Van Guilder Patent N 0. 1,250,394, granted December 18, 1-917, although other types of wall molding ,or building machines or the like maybe employed in connection with my said invention.

Each of the wall molding machines and 11 shown'comprises outer walls 12, 12" havmg hopper extensions or portions 13 at the ion to permit of the upper edges thereof. The walls 12, 12 are supported by the uprights or brackets 14, 14 secured to the outer sides thereof at the ends, and extending upwardly through the hopper portions 13.

Relative movement of the outer walls 12, 12 away from and towards each other, is effected by means of the angle irons or members 15 and 16, disposed one upon the other and arranged in pairs at the opposite ends of each machine. The members 15 and 16 are maintained in. sliding relation by means of the bolts 1'? carried by the lower member 16 and operating in the slots 18 of the upper member 15.

The brackets or members 1 1 and 141; are secured at their upper ends to the outer faces of the sliding members 16 and 15 by means of bolts or other suitable securing means 19.

Intermediate the outer walls 12, 1 of each machine is disposed a collapsible core 20 consisting of the walls 21, 21 having in wardly directed overlapping flange portions 22 and 23 at the top and bottom thereof, substantially closing the core 20 at the top and bottom to prevent access of the building material to the interior thereof, the overlapping portions 22 and 23 being in slidable engagement to permit of the relative movement of the walls 21, 21" tmrards and away from each other.

The walls 21., 21 are suppor ed by means of the uprights or brackets 2 1, 2.45 secured to the inner faces of said walls 21, 21 at the ends thereof, and carried by and secured to the slide bars 16 and 15 like the brackets 141-, 14 are.

Relative movement between the walls is effected by means of an actuating member 25 having arms 26 pivoted at their outer ends 27 to the lower slide bars 16 at corresponding ends thereof. Links 28 are pivoted at corresponding ends 29 to the opposite ends of the upper slide bars 15, and at their opposite ends 30 said links are pivotally connected to intermediate portions of said arms 26.

The swinging of the actuating member 25 moves the walls 12 and 21 and the walls 12 and 21 in opposite directions, the actuation of said member 25 in one direction moving the walls 12, 12 inwardly and the walls 21, 21 outwardly, and the actuation of said member in the opposite direction causing the reverse movement of said walls.

Each core 20 is maintained in operative position against inward movement of the walls thereof by means such as the follow ing: The upright or bracket 2 1 at its lower end within the core 20 is provided with an inwardly projecting beveled lug or portion 31, and the upright or bracket 24 is provided with a pair of similar beveled lugs 32 projecting inwardly at the opposite side of the core 20, and in vertical planes oppo- 32 and serve to prevent the inward inovement of said walls during the lumping op- !IT j 1 oration. 1 he flanges 36 on the parts 30 serve to retain the latter in operative relation with the lugs 31, 32.

Each mach ne 10 and 11 is provided with auxiliary wall portions, or slides 3'7 and 33 guided between the uprights 1 1 and 1% am,

the walls 12 and 12,'and forming extensions of said walls.

As shown at 1, a pair of machines may be ennployed to form corners, pilasters, chimneys, lines or other portions, the machines being arranged at various angles, according to the angularity of the wall portion to be formed, or according to the nature of the portion to be constructed. At Fig. 1, as one example, the machines are arranged to form a. corner, and for this purpose, the extensions or slides 37 and 33 are drawn out to form the angular space in which the corner of the portion is to be formed. The adjacent ends of the extension 37 are preferably secured together by suitable means 39.

For forming an air space within the corner portion of the wall, an angular core 4i-O is provided adapted to form with too cores 20 of the machines a continuous air space in the portion of the wall to be formed within the mold system.

The angular core 40 comprises a pair of angular walls 411, 12, movable towards and away from each other, and her ing inwardly directed flanges 13 at the top overlapping each other in slidable engagement, and providing a closed top for preventing access of the plastic or other material to the interior thereof.

The lower portions of the walls 41, 4-2, are reinforced by the inwardly directed flange portions 1 1 which terminate inwardly of the opposite ends of the core walls, as indicated at 45. The opposite ends 16 of the core 410 are open to permit of the reception of the ends of the cores 20 of the adjacent machines between the core walls 11, 4 2.

The core 10 is actuated. or controlled by a reciprocating member 17 disposed between the walls 41 and 42 and projecting through the closed top of the core to provide a handle. Brackets i3 are secured to the upper and lower inner portions of each wall 11, 12

at the anglethereof. Connections are made between said reciprocating actuating member 47 and said brackets 48, through the links 49 pivoted at their outer ends to said brackets and at their inner ends t0 suitable lugs 50 carried by said actuating member.

When the actuating member 47 is moved from the position shown at Fig. 6 to the position shown at Fig. the contiguous portions 51 of the links 49 and the lugs 50, constituting stops, engage eachother to maintain said links in alignment and said walls inoperative position, and held against in ward movement towards each other by said actuating means. 4

The outer ends of the cooperating walls of: the cores 20, received between the core walls 41 and 42, serve to maintainthe outer ends of'the core walls 41 and 42 in operative position against inward movement, the cores 20 being held in that position by the members WVhen the member 47 is actuated in the opposite or upward direction, after first actuating the machines and 11 to collapse the core walls of the cores 2(), the core walls 41 and 42 move inwardly towards each other, the upward movement of the member 47 being limited by the stops 52 carried thereby and adapted in the upper position of the actuating membe' 47, to engage the links 49.- The core 40 can then be readily removed or lifted from the air space in the newly formed wall without damaging or injuring the latter.

In operation, the machines 10 and 11 are disposed in the desired relation according to the shape of the wall portion to be built. The core 40 is then actuated to expand the same, and is placed into position with the ends of the cores extending into the ends of the same. The machines are then actuated to place the Walls thereof into operative position, the core portions20 with the actuating means of the core 40 serving to main.- tain the walls of the latter against inward movement.

- The plastic building material or concrete is now introduced into the mold and suitably tamped. The operating members are now actuated to move the walls 12 and 12 away from each other and the walls 21, 21 towards each other. The core is then actuated to move the walls thereof towards each other, and the same can then be lifted out of position.

In my invention the core walls are actuated by means disposed between the same and connected thereto at the upper and lower portions thereof. By this arrangement the forces tending to expand or collapse the core are applied at points located within the confines of said core and arranged symmetrically relative thereto. Hence, the operation of the core is facilitated, and binding or other torsional stresses are obvireadily placed in position, and may be readily removed, when the wall portion has been completed, without danger of scraping over the newly molded soft construction and damaging the same.
